System and method for forming and moving an article array

ABSTRACT

A system for forming and moving an article array including a consolidation area having a support surface for receiving and arranging rows of articles to form an article array from an article row delivery device while the consolidation area continuously stabilizingly supports the periphery of the article rows positioned on the support surface as the article rows are arranged to form the article array.

FIELD OF THE INVENTION

The present invention is directed to a system and method for equipment associated with loading and unloading palletizing article arrays or portions thereof.

BACKGROUND OF THE INVENTION

When large numbers of stackable articles must be transported in large quantities to another location, especially when the article is small, the article may be packaged in a container to protect the article during shipping of the container. Alternately, to reduce the amount of handling required and/or to reduce the amount of shipping material consumed, the articles may be arranged in a tight grouping, or array, of articles. Each array of articles can form a layer of articles that can be stacked on a pallet having a footprint which can be accommodated by freight hauling compartments, e.g., for truck, rail, sea or air vessels.

Palletizing articles is becoming increasingly automated in manufacturing facilities, wherein articles are moved via a conveyor, which articles are manipulated by dedicated machinery onto pallets.

It would be beneficial to develop and use a system and method for loading/unloading article array heads.

BRIEF DESCRIPTION OF THE INVENTION

In an embodiment, a method for forming and moving an article array includes receiving a first row of articles onto a support surface of a consolidation area between a movable stabilizer and a movable backing plate, the consolidation area providing continuous stabilizing support to the periphery of the first row of articles, the stabilizer and the backing plate providing stabilizing support to opposed portions of the periphery of the first row of articles. The method further includes the backing plate and the stabilizer moving and stabilizingly supporting the first row of articles in a first direction. The method further includes additionally stabilizingly supporting the portion of the periphery of the first row of articles stabilizingly supported by the backing plate, the additional stabilizing support being independent of the stabilizing support provided by the backing plate. The method further includes moving the backing plate in a direction opposite the first direction in preparation of receiving a second row of articles. The method further includes receiving the second row of articles immediately adjacent the first row of articles onto the support surface between the backing plate and the first row of articles, the periphery of the first row of articles and the second row of articles being continuously stabilizingly supported, including stabilizing support provided by the stabilizer and the backing plate, the first row of articles and the second row of articles forming an article array. The method further includes removing the additional stabilizing support from the portion of the periphery of the first row of articles formerly stabilizingly supported by the backing plate, the portion of the periphery of the first row of articles formerly stabilizingly supported by the backing plate being stabilizingly supported by a corresponding portion of the periphery of the second row of articles, and a portion of the periphery of the second row of articles being stabilizingly supported by the backing plate. The method further includes moving the article array toward a collection area.

In another embodiment, a method for forming and moving an article array including receiving a first row of articles onto a support surface of a consolidation area between a movable stabilizer and a movable backing plate, the stabilizer and the backing plate each having an axis along its length, the first row of articles being received from a direction that is substantially perpendicular to each axis of the stabilizer and the backing plate, the consolidation area providing continuous stabilizing support to the periphery of the first row of articles, the stabilizer and the backing plate providing stabilizing support to opposed portions of the periphery of the first row of articles. The method further includes the backing plate and the stabilizer moving and stabilizingly supporting the first row of articles in a first direction from the same direction as the first row of articles. The method further includes additionally stabilizingly supporting the portion of the periphery of the first row of articles stabilizingly supported by the backing plate, the additional stabilizing support being independent of the stabilizing support provided by the backing plate. The method further includes moving the backing plate in a direction opposite the first direction in preparation of receiving a second row of articles from the same direction as the first row of articles. The method further includes receiving the second row of articles immediately adjacent the first row of articles onto the support surface between the backing plate and the first row of articles, the periphery of the first row of articles and the second row of articles being continuously stabilizingly supported, including stabilizing support provided by the stabilizer and the backing plate, the first row of articles and the second row of articles forming an article array. The method further includes removing the additional stabilizing support from the portion of the periphery of the first row of articles formerly stabilizingly supported by the backing plate, the portion of the periphery of the first row of articles formerly stabilizingly supported by the backing plate being stabilizingly supported by a corresponding portion of the periphery of the second row of articles, and a portion of the periphery of the second row of articles being stabilizingly supported by the backing plate. The method further includes moving the article array to a collection area.

In yet another embodiment, a system for forming and moving an article array including a consolidation area having a support surface for receiving and arranging rows of articles to form an article array from an article row delivery device while the consolidation area continuously stabilizingly supports the periphery of the article rows positioned on the support surface as the article rows are arranged to form the article array. The consolidation area including a backing plate and a first stabilizer, the article rows positioned between the backing plate and first stabilizer, the backing plate and the stabilizer providing stabilizing support to opposed portions of the periphery of the article rows. Upon the first stabilizer and the backing plate moving and stabilizingly supporting the article rows in a first direction while forming the article array, a second stabilizer provides independent stabilizing support to the portion of the periphery of the article rows stabilizingly supported by the backing plate prior to the backing plate moving in a direction opposite the first direction, in preparation of receiving additional article rows in the consolidation area immediately adjacent the article rows already positioned on the support surface for forming the article array. Upon formation of the article array, the second stabilizer discontinues providing stabilizing support to the portion of the periphery of article rows formerly stabilizingly supported by the backing plate, the portion of the periphery of the first row of articles formerly stabilizingly supported by the backing plate being stabilizingly supported by a corresponding portion of the periphery of the additional rows of articles, and a portion of the periphery of the additional row of articles being stabilizingly supported by the backing plate. An article array moving device is provided for moving the article array from the consolidation area toward the collection area.

DETAILED DESCRIPTION OF THE INVENTION

Referring to FIG. 1, an automated palletizer system or palletizer 10 utilizing an article array forming/moving system 12 is shown. Article array forming/moving system 12 receives articles 14 (FIG. 4), and more specifically, article rows 16 (FIG. 4) from an article row delivery device 18, such as a conveyor for forming article arrays 22 (FIG. 18) that are moved to a collection area 26 (FIG. 1) such as a container or a tray (e.g., having a bottom surface and short peripheral walls extending upwardly from the bottom surface), by a article array moving device 28 movable by an anthropomorphic robotic arm 30. As shown in FIG. 1, once container or collection area 26 is filled with article arrays 22 and closed, the container or collection area 26 is moved via a conveyor 32 for shipping. In other palletizing embodiments, the components may by arranged differently. Other exemplary embodiments of associated components of palletizer 10 will be discussed in further detail below.

For purposes herein, the term “article row” may be used irrespective the number of articles rows being gripped, moved or otherwise manipulated. In other words, the term “article row” may be used irrespective a single row of articles or article row 16 (FIG. 22), a pair of rows of articles or article row pairs 17 (FIG. 18) or more than two pairs of article rows or an array of articles or article array 22 (FIG. 4) being gripped, moved or otherwise manipulated. Similarly, the term “article array” may refer to two or more article rows, although the term “partial article array” may be used to refer to an article array already having two or more article rows, but undergoing further loading or building of article rows, thereby further building, loading or enlarging the existing article array. The terms “gripped” and “manipulated” and “moved” and the like in the context of the interaction between the article row delivery device and the article row(s) may be used interchangeably.

FIG. 2 shows an article array forming/moving system 112 configured to receive successive article rows 16 (FIG. 22) from article row delivery device 118 for forming the article array 22 (FIG. 29) in consolidation area 138 prior to moving the article array 22 to collection area 126, such as a bagging area.

FIG. 3 shows an article array forming/moving system 112 configured to receive successive article rows 16 (FIG. 22) from article row delivery device 118 for forming the article array 22 (FIG. 29) in consolidation area 138 prior to moving the article array 22 to collection area 226, such as onto a slip sheet 172 (FIG. 34).

FIG. 4 shows article array forming/moving system 12 that is configured to receive an article row pair 17 or pair of article rows 16 from article row delivery device 18. As shown in FIG. 4, article row delivery device 18 is a conveyor used in combination with an article row handling device 34. Article row handling device 34 receives article row pair 17 from article row delivery device 18, and then places the article row pair 17 onto a support surface 36 of a consolidation area 38. In another embodiment, the article row delivery device can include an article array head, such as article array moving device 28 (FIG. 1) used in combination with an article row delivery device 18 or other article row delivery source.

FIGS. 5-17 sequentially show the operation of article array forming/moving system 12 (FIG. 4). It is to be understood that the exemplary sequential operation movements shown in FIGS. 5-17 (as well as other exemplary operational movements discussed in further detail below) may at least partially occur simultaneously or in an order different than that discussed. As shown in FIG. 5, the exemplary article row handling device 34 includes a clamping head 40 having a pair of gripping jaws for engaging each article row 16 of article row pair 17 received from article row delivery device 18. In one embodiment, the clamping head may be able to engage a different number of article rows, such as the number of article rows provided from the article row delivery device.

Once clamping head 40 engages article row pair 17 received from article row delivery device 18, then as shown in FIG. 6, article row handling device 34 raises article row pair 17 in a vertical direction 42 away from article row delivery device 18.

Once article row handling device 34 raises article row pair 17 away from article row delivery device 18, then as shown in FIG. 7, article row handling device 34 moves article row pair 17 in a horizontal direction 44 away from article row delivery device 18 until article row pair 17 is vertically positioned over a support surface 36 of consolidation area 38 and between a backing plate 46 and a stabilizer 48. Consolidation area 38 includes support surface 36, backing plate 46 and stabilizer 48 and other components as will be discussed in further detail below.

Once article row pair 17 is vertically positioned over support surface 36 of consolidation area 38 and between backing plate 46 and stabilizer 48, then as shown in FIG. 8, clamping head 40 of article row handling device 34 moves article row pair 17 in a vertical direction 42 between backing plate 46 and stabilizer 48 until article row pair 17 contacts and is vertically supported by support surface 36 of consolidation area 38.

Once article row pair 17 contacts and is vertically supported by support service 36 of consolidation area 38, then as shown in FIG. 9, clamping head 40 of article row handling device 34 is disengaged from article row pair 17 and moves in vertical direction 42 away from the article row pair. As a result, article row pair 17 is vertically supported by support surface 36 and the periphery of article row pair 17 is stabilizingly supported by consolidation area 38, which includes backing plate 46, stabilizer 48, and opposed support members 50 (FIG. 4).

For purposes herein, “stabilizingly supported” and variations thereof refer to support provided to at least the periphery of the article row(s) such as to prevent tipping of the articles. For example, such stabilizing support may include, but is not limited to lateral support, including support forces directed substantially perpendicular to the support surface of the consolidation area, and vertical compressive support forces applied to opposed ends of the article row(s), such as applied by clamping head 40 to corresponding ends of article row pair 17 opposite support surface 36, such as shown in FIG. 8.

Once clamping head 40 of article row handling device 34 is disengaged from article row pair 17, and vertically moved away from article row pair 17, then as shown in FIG. 10, article row handling device 34 moves in horizontal direction 44 away from article row pair 17 in preparation of engaging another article row pair 17 received from article row delivery device 18 (FIG. 5) as previously discussed.

Once article row handling device 34 moves away from article row pair 17, then as shown in FIG. 11, backing plate 46 and stabilizer 48 move and stabilizingly support opposed portions of the periphery of article row pair 17 (FIG. 10) in a horizontal direction 44 away from article row handling device 34, becoming already positioned article rows 19, with support members 50 (FIG. 4) of consolidation area 38 providing stabilizing support of the remaining portions of the periphery of already positioned article rows 19. In other words, article row pair 17 and already positioned article rows 19 are each continuously stabilizingly supported by the backing plate 46, stabilizer 48 and consolidation area 38.

Once article row pair 17 has been moved and continuously stabilizingly supported to become continuously stabilizingly supported already positioned article rows 19, then as shown in FIG. 12A, stabilizer 52 moves a stabilizer bar 56 in vertical direction 42 until stabilizer bar 56 achieves a stabilizing position 54, applying a vertical compressive stabilizing force to at least a portion of the periphery of the already positioned article rows 19. Stabilizer 52 provides an additional, independent stabilizing support to at least the portion of the periphery of the already positioned article rows 19 simultaneously stabilizingly supported by backing plate 46. Article row handling device 34 moves another article row pair 17 in horizontal direction 44 toward already positioned article rows 19.

Once stabilizer bar 56 achieves stabilizing position 54, then as shown in FIG. 12B, backing plate 46 moves in horizontal direction 44 away from the already positioned article rows 19, and article row handling device 34 moves article row pair 17 in horizontal direction 44 until article row pair 17 is immediately adjacent to already positioned article rows 19 and vertically positioned between backing plate 46 and the already positioned article rows 19.

Once article row pair 17 is immediately adjacent to already positioned article rows 19, then as shown in FIG. 13, clamping head 40 of article row handling device 34 moves in vertical direction 42 between backing plate 46 and already positioned article rows 19 until article row pair 17 contacts and is vertically supported by support surface 36 of consolidation area 38. As a result of this arrangement, article row pair 17 being immediately adjacent to already positioned article rows 19, article row pair 17 stabilizingly supports already positioned article rows 19, becoming a portable article array 20. In one embodiment, article row pair 17 contacts and compressively secures already positioned article rows 19 while becoming partial article array 20. Opposed portions of the periphery of partial article array 20 are stabilizingly supported by backing plate 46 and stabilizer 48, as well as support members 50 (FIG. 4) stabilizingly supporting the remaining portions of the periphery of partial article array 20. As a result, partial article array 20 is continuously stabilizingly supported by backing plate 46, stabilizer 48 and consolidation area 38.

Once partial article array 20 has been formed, then as shown in FIG. 14, stabilizer bar 56 is moved in vertical direction 42 away from and disengaging partial article array 20. In one embodiment, stabilizer 52 is moved in one or more of vertical and horizontal directions such that the stabilizer is moved out of the path of an article array prior to the article array reaching a collection area, as will be discussed in further detail below. Despite disengagement from stabilizer bar 56, partial article array 20 is continuously stabilizingly supported by backing plate 46, stabilizer 48 and consolidation area 38.

Once stabilizer bar 56 has been disengaged from partial article array 20, then as shown in FIG. 15, backing plate 46 and stabilizer 48 move and stabilizingly support opposed portions of the periphery of partial article array 20 in a horizontal direction 44 away from article row handling device 34 in preparation of adding additional article row pair(s) 17, such as previously discussed and shown in FIGS. 11-14. The periphery of partial article array 20 is continuously stabilizingly supported by the backing plate 46, stabilizer 48 and consolidation area 38, as previously discussed.

FIG. 16 shows a fully formed or completely built-up or loaded article array 22 that is continuously stabilizingly supported by consolidation area 38, having been continuously stabilizingly supported during the build-up or loading of article array 22.

Once article array 22 has been formed, then as shown in FIG. 17, backing plate 46 and stabilizer 48 move and stabilizingly support opposed portions of the periphery of article array 22 in horizontal direction 44 away from stabilizer 52 in preparation of moving article array 22 to collection area 26 (e.g., FIG. 1). FIG. 20A is a plan view of the periphery of article array 22 continuously stabilizingly supported by the backing plate 46, stabilizer 48 and consolidation area 38, as previously discussed, having a distance 58 between backing plate 46 and stabilizer 48. FIG. 20B is a plan view of the periphery of article array 22 that is similar to FIG. 20A, except that backing plate 46 and stabilizer 48 are moved toward each other such that the distance therebetween is reduced, such as to a distance 60, thereby reducing the vertical cross section of article array 22. It may be desirable to reduce the vertical cross section of article array 22 when the article array moving device 28 utilized is an article array head, as shown in FIG. 18 for reasons such as facilitating moving the article array to a collection area 26, such as inside of a container having an opening of a fixed size. Upon being moved inside the container, the article array cross section would elastically increase to the extent possible inside of the container, providing increased stability of the article array inside of the container.

Once article array 22 has been moved, then as shown in FIG. 18, article array moving device 28, such as an article array head is vertically aligned with article array 22.

Once article array moving device is vertically aligned with article array 22, then as shown in FIG. 19, article array moving device 28 is moved in vertical direction 42 until engaging article array 22. FIG. 21 shows article array moving device 28 lifting and moving article array 22 from support surface 36 of consolidation area 38 toward a collection area 26 (FIG. 1).

In one embodiment, stabilizer 52 may be moved in one or more of vertical and horizontal directions such that stabilizer 52 is moved out of the path of article array 22 prior to the article array 22 reaching a collection area. For example, such as shown in FIG. 15, if stabilizer 52 were moved such that article array 22 is vertically accessible by article array moving device 28 (FIG. 18), it may be possible to eliminate further movement of the article array, as shown in FIG. 18, i.e., the backing plate 46 and stabilizer 48 moving and stabilizingly supporting opposed portions of the periphery of article array 22 in horizontal direction 44 away from stabilizer 52 in preparation of moving article array 22 to collection area 26 (e.g., FIG. 1).

FIGS. 22-28 sequentially show the operation of article array forming/moving system 112, such as shown in FIG. 2. It is to be understood that the exemplary sequential operation movements shown in FIGS. 22-28 may at least partially occur simultaneously or in an order different than that discussed. As shown in FIG. 22, article row 16 is received from article row delivery device 118, such as a conveyor. In one embodiment, article row delivery device 118 may provide more than one article row 16.

Once article row 16 is received from article row delivery device 118, as further shown in FIG. 22, article row 16 is stabilizingly supported by backing plate 146 and stabilizer 152.

Once article row 16 is stabilizingly supported, then as shown in FIG. 23, stabilizer 152 is moved in vertical direction 142 until stabilizer 152 is in a retracted position that is substantially flush with the surface of article row delivery device 118 and support surface 136 of consolidation area 138. In one embodiment, stabilizer 152 may be rotated to achieve a retracted position that is substantially flush relative to the surface of article row delivery device 118 and support surface 136. By virtue of the close proximity of stabilizer 152 and stabilizer 148, even with stabilizer 152 retracted, the periphery of article row 16 remains continuously stabilizingly supported by backing plate 146, stabilizer 148 and consolidation area 138. Consolidation area 138 includes support surface 136, backing plate 146, stabilizer 148, support members 150 (FIG. 29) and other components as will be discussed in further detail below.

Once stabilizer 152 is in a retracted position, then as shown in FIG. 24, backing plate 146 and stabilizer 148 move and stabilizingly support opposed portions of the periphery of article row 16 in a horizontal direction 144 away from article row delivery device 118 and over retracted stabilizer 152. Article row 16 is then further moved in a horizontal direction 144 until reaching an extended predetermined position 160 (FIG. 25).

Once article row 16 reaches extended predetermined position 160, then as shown in FIG. 25, stabilizer 152 is moved in vertical direction 142 to an extended position either prior to or substantially simultaneously with backing plate 146 moving in horizontal direction 144 away from article row 16, until backing plate 146 reaches a starting position or home position 162. In either event, stabilizer 152 provides an additional, independent stabilizing support to at least the portion of the periphery of article row 16 simultaneously stabilizingly supported by backing plate 146.

Once stabilizer 152 is in an extended position and backing plate 146 is in home position 162, then as shown in FIG. 26, an additional article row 16 is received from article row delivery device 118, the article rows 16 becoming an article row pair 17.

Once article row pair 17 has been formed, then as shown in FIG. 27, stabilizer 152 is moved in vertical direction 142 to its retracted position.

Once stabilizer 152 is retracted, then as shown in FIG. 28, backing plate 146 and stabilizer 148 move and stabilizingly support opposed portions of the periphery of article row pair 17 in a horizontal direction 144 away from article row delivery device 118 and over retracted stabilizer 152, article row pair 17 becoming partial article array 20. Depending upon the geometry of the articles, such as a circular cross section, adjacent article rows may partially overlap one another to form a more compact, stable arrangement, such as shown in FIG. 29 for article array 22.

Once partial article array 20 has been formed, additional article rows 16 are added, such as previously discussed and shown in FIGS. 25-28, forming article array 22 as shown in FIG. 29.

Once article array 22 has been formed, then as shown in FIG. 30, backing plate 146 and stabilizer 148 move and stabilizingly support opposed portions of the periphery of article array 22 in a horizontal direction 144 toward an end 164 of support surface 136 of consolidation area 138 in preparation of moving article array 22 from consolidation area 138 to a collection area 126, 226 (see respective FIGS. 2, 3). The periphery of article array 22 is continuously stabilizingly supported by backing plate 146, stabilizer 148, and consolidation area 138, which includes support members (FIG. 29), as previously discussed.

As shown in FIG. 31, as backing plate 146 and stabilizer 148 move and stabilizingly support opposed portions of the periphery of partial article array 20 in horizontal direction 144 toward end 164 of support surface 136 of consolidation area 138 in preparation of moving article array 22 from consolidation area 138 to a collection area 126, 226 (see respective FIGS. 32, 34), stabilizer 148 selectively retracts in a vertical direction 142, becoming substantially flush with support surface 136.

As shown in FIG. 32, which is an extended side view of FIG. 31, article array 22 is moved in horizontal direction 144 toward collection area 126, which is a bagging area. As further shown in FIG. 32, the periphery of article array 22 in close proximity to retracted stabilizer 148 is continuously stabilizingly supported as a result of its close proximity to film 170 of bagging area or collection area 126. FIG. 33 shows article array 22 further directed into collection area 126 and further surrounded by film 170, ultimately becoming a bagged article array (not shown).

FIG. 34 is similar to FIG. 33, except that article array 22 is being directed into collection area 226, such as an area including a slip sheet 172. A further difference with collection area 226 is that an additional stabilizer 174 is required to ensure article array 22 is continuously stabilizingly supported while being moved from consolidation area 138 to collection area 226.

FIG. 35 shows an embodiment of consolidation area 138 in which portions of support surface 136 are pivotably connected to corresponding actuators 168. During normal operation, actuators 168 are maintained in an extended position, securing the portions of support surface 136 in a horizontal position for supporting an article array. However, for reasons such as partial tipping of articles of the article array 22, the presence of defective articles or for other reasons, actuators 168 are selectively urged toward a retracted position such that at least sufficient portions of support surface 136 subtend an angle with a horizontal plane sufficient to remove all articles on the portions of support surface 136 by force of gravity, thereby preventing all articles of the article array 22 from being movable to the collection area. This support surface construction resembles bombardier doors of an aircraft. In another embodiment, a single actuator may be utilized to support a support surface of unitary construction. In another embodiment, support surface 136 may include more than two portions, each having corresponding actuators.

While the invention has been described with reference to one or more embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the invention without departing from the essential scope thereof. Therefore, it is intended that the invention not be limited to the particular embodiment disclosed as the best mode contemplated for carrying out this invention, but that the invention will include all embodiments falling within the scope of the appended claims.
